There are different heat response of acids in baking (McGee discusses this and I think the other link does. I find the topic fascinating but should stop my [merail])…
Is the book approximately relevant to women in Canada? Or, are there some points of correspondence but overall too many differences to be wholly relevant?
I am appreciating the chemistry stuff, it's always nice to learn something new which you thought you already knew about!
Canada is probably more similar to the US in terms of the history of the people who live there. It's really only in the War of Independence that you can even think about the countries development separately - a lot of Canada's early black population were in fact loyalists who came from what had become the US, and were settled into land grants, though there were certainly also some other people of African origin too. But the black loyalists in general would have been slaves or poor and so many of their descendants today connect with that history and also with that culture - most are Baptists, for example.
On the other hand, we never had the slave economy of the southern US, the number of black Canadians was never anything like the US where you have cities and states with a significant % of the people who are black, and our laws followed the British laws. Culturally, for a long time Canada was more British and European in its associations than American, however this changed markedly with the EU, the Commonwealth becoming less important, and American tv and music becoming dominant. This older black population has many of the same problems associated with the American population, including being poor, bad relations with police, etc, though I think our better social safety net has helped.
We've also had the same inundation of identity politics as the UK has coming from across the border, including all the less savoury parts, applied to black population and native peoples. At first glance it does seem like it would be a better fit here because of the shared history, but in the end, I don't think it is. It still seems to impose a narrow and sometimes even bizarre lens on our own history, a deliberate (or deliberately ignorant) massaging to fit the narrative.
But - I think that happens in the US too, which is why you have historians critising the 1619 project as being a-historical.
